Limiting values
[1]
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2]
For DIP16 packages: above 70
C the value of P
tot derates linearly at 12 mW/K.
For SO16 packages: above 70
C the value of P
tot derates linearly at 8 mW/K.
For SSOP16 and TSSOP16 packages: above 60
C the value of P
tot derates linearly at 5.5 mW/K.
